    Brand New High JJ ECC803S / Long Plate 12AX7 Vacuum Tubes - Matched Quad
    We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ
    The JJ ECC803S / 12AX7 Long Plate is a high gain tube. The long plates make for higher gain and a warmer fuller tone but they also increase the chance of microphonics so these are best used in guitar amplifiers or other high gain applications. Almost every sought after vintage tube has long plates so the tonal differences are worth the risk. These are comparable to the Telefunken ECC803S which is the tube that JJ had in mind when they designed it.
    Testing and/or Matching
    We test and/or match our tubes by Gm & Plate Current using a state of the art digital Maxi-Matcher tube tester. The Maxi-Matcher simulates a real circuit and tests tubes in real-world conditions. We also check our tubes for other issues like shorts on calibrated and vintage tube testers. We match our tubes +/- 5% with an overall tolerance of 10%.
    While we do screen for noise and microphonics, even the best tube testers are quite bad at finding these faults. The only real test is with your ears. We guarantee that our tubes will be free of noise or microphonics but please be aware that there isn't a whole lot we can do to ensure your tube won't be. To combat this issue, we are quite liberal in accepting returns for these reasons.
